General The apparatus has to be operated according to the appropriate data in the data
sheet and in this instruction manual.
The EC-Type Examination Certificate has to be observed.
The special conditions must be adhered to!
Maximum housing surface temperature The maximum surface temperature of the housing is given in the EC-Type Exami-
nation Certificate.
Installation, Comissioning Laws and/or regulations and standards governing the use or intended usage goal
must be observed.
The intrinsic safety is only assured in connection with an appropriate related
apparatus and according to the proof of intrinsic safety.
The associated apparatus must satisfy at least the requirements of category ia IIB
or iaD. Because of the possibility of the danger of ignition, which can arise due to
faults and/or transient currents in the equipotential bonding system, galvanic isola-
tion in the power supply and signal circuits is preferable. Associated apparatus wit-
hout electrical isolation must only be used if the appropriate requirements of IEC
60079-14 are met.
The intrinsically safe circuit has to be protected against influences due to lightning.
When used in the isolating wall between Zone 20 and Zone 21 or Zone 21 und
Zone 22 the sensor must not be exposed to any mechanical danger and must be
sealed in such a way, that the protective function of the isolating wall is not
impaired. The applicable directives and standards must be observed.
If the Ex-relevant identification is exclusively printed on the included adhesive label,
this must be applied in the direct vicinity of the sensor! The surface to which the
label is to applied must be clean and free from grease! The applied adhesive label
must be durable adlegible to protect it against the possibility of chemical corrosion!
Maintenance No changes can be made to apparatus, which are operated in hazardous areas.
Repairs to these apparatus are not possible.
Specific conditions
Electrostatic charging
The connection cables are to be laid in accordance with EN 50281-1-2 and must not
normally be subjected to chaffing during use.
